Cracked teeth can be tiny and unnoticeable, or they can be glaring and cause a lot of discomfort. But even microcracks require attention. The fact is that the environment in the oral cavity is aggressive, there are constant chemical reactions, temperature changes, teeth are subjected to mechanical impact. Small cracks can turn into a major problem. Through enamel damage, pigments stain the dentin and the teeth acquire different shades, each one - its own. As the crack deepens, it can reach the dentin, provoking tooth hypersensitivity. And if the fracture deepens and touches the pulp, complications such as pulpitis, abscess and even tissue necrosis develop.

The American Association of Endodontists distinguishes the following groups of cracks[1]:

Often discovered incidentally during regular visits to the dentist. Treatment has the most favorable prognosis. Some microcracks, such as those that occur afte…

We use the expression "gnashing our teeth" most often in a figurative sense when describing rage. However, for some people it is a real problem that causes a lot of trouble. It's called bruxism. Bruxism in adults is uncontrolled grinding of teeth. It occurs due to spasm of the masticatory muscles. The jaws clench and rub against each other. A distinction is made between daytime and nighttime bruxism. With age, its incidence decreases. Nevertheless, nighttime teeth grinding occurs in about 13% of adults and 22% of adults during the day [1]

Distinguished:

In dentistry, there is no consensus on this issue. They distinguish not separate causes of bruxism, but entire groups:

Hyperesthesia or hypersensitivity of the teeth is pain that occurs in response to temperature, chemical, tactile stimuli. Characteristics:

Hyperesthesia is caused by thinning enamel. The dentin underneath is no longer protected and responds to irritation. Another cause may be gingival recession. In this case, the root is exposed and reacts.

In Russia, hypersensitivity affects 62% of the population [1]. The problem mainly occurs between the ages of 30 and 60.

Dentistry identifies several factors that affect the increase in sensitivity:

This can be caused by functional disorders (bruxism) or physical impact (chewing nuts, breadcrumbs, hard candies)

Horizontal movements during brushing can lead to a serious problem s…

Everyone's teeth wear down as they age. Hard tissue is lost due to friction between surfaces and food. In most cases, this process is uniform, takes a long time and does not affect chewing function. It is a natural (physiological) loss of hard tissue. But sometimes the loss of enamel and dentin (the layer beneath the enamel) is so intense that they talk about pathological erasability of teeth (abrasion). This process leads to physiological disorders and affects all aspects of life.

At first, the disease is asymptomatic, so it is diagnosed in a neglected state. When the tooth enamel erodes and dentin becomes involved, patients begin to complain of hypersensitivity. Teeth react to temperature (hot, cold), chemical (sour, sweet), mechanical (touch of toothbrush) stimuli, causing inconvenience in everyday life.

Destruction of dentin leads to root inflammation (periodontitis), bone atrophy.

Visited the dentist, had your teeth treated and after a while it started bothering you again? The cause may be secondary caries under the filling of the tooth. The situation is unpleasant, but quite common. Unfortunately, for a long time the carious process is asymptomatic. Patients begin to notice that the filling has changed color, broke off, the tooth began to react to temperature stimuli, when the disease has developed to a deep stage.

The main cause is the same as in primary caries: the penetration of bacteria through the protective barrier. This barrier in the treated tooth is the filling. As soon as its integrity is compromised, problems arise. Bacteria are able to penetrate a microcavity 50 microns wide. They begin to multiply, eating away at the hard tissue.

Factors provoking secondary tooth decay:

Caries is a non-infectious disease. It is characterized by the leaching of minerals from the hard tissues of the tooth and the formation of carious cavities. The initial degree is caries in the stain stage. At this stage, the disease can be treated with therapeutic methods, without a drill.

Unfortunately, the only sign of chalky caries is a spot on the enamel. It does not give painful sensations, only occasionally it can react to chemical irritants. There are no definite symptoms. It is difficult to see it, especially on the side teeth. Therefore, the initial caries in the stain stage often goes unnoticed. The doctor is consulted when the disease reaches the stage of medium or deep decay, involving the dentin and cementum of the tooth.

That's why, it's important to visit the dentist regularly. The doctor will not just see a chalky stain,…
